Okay, as to the very detailed and (for the chemistry deficient) very confusing answer from 'reut', I have a couple of follow-up questions, and I will ask you to pardon my ignorance...  With arguably one of the best holidays of the year coming up quickly, I am trying to think outside the box for a costume.  For the past 3 or 4 years, I have found that a couple of battery powered blacklights and a few yellow highlighters make for a very interesting party tool.  (Sorry for going off on a tangent!!)  I want to incorporate the 'glow-in-the-dark' liquid on hair, skin, (expendable) clothing, etc.

1.  Considering that I will have on, for one night, approximately 3-4 hours, is this an incredibly dangerous idea to use this liquid on hair, skin, clothing, etc.?

2.  Will the liquid dry? (Concern to keep it from transferring to others, or floors/furniture)  I guess I just don't want it to be 'too messy'.

3.  With exception to colors, are there any major differences in glowsticks?

Thanks, in advance, for any assistance.
